tors, of w To all whom. itvnay concern:

. Be itknown that I, BYRON E. VAN Annex, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Innrovements in Valves for Radiol llC-ll the following, when taken in connection with the drawing accompanying and forming a part hereof, is a full and complete description sufiicient to enable those skilled'in the art to which it pertains to understand, make, and use the same.

This invention relates to valve mechanism for discharging air and water of condensation from steam heatin systems by differential pressure and one 0t the objects of the invention is to provide means whereby the float chamber and the well or sealing chamber may, resoectivel be cleaned of any dirt deposited therein y the operation of the device,. without materially increasing the cost of construction over the cost thereof when 1- no means are provided for cleaning both the float chamber and the well.

"wA further object ofthis invention is to prof-ylde a construction wherein the valve seat andvalve co-acting therewith which controls thefiow of water of condensation from the c anics.

float chamber, in the automatic operation of .G

the device, together with the float and float guide may be easily and correctly assembled articularl skilled in-mc And a urther ob ect is to provide a. construction wherein the valve seat and valve co-acting therewith will be maintained clean and in operative condition by the automatic o eration of the device.

1n the rawin referred to a vertical secpersons not tional view of a device embodying these features is shown.

J, J, is an outwa dly flaring wall, extend ing upwardly from velveseat ll to the rim A ccnicalrecess the upper edge whereof is located above the bottom of the float chamher, with the valve seat'et the bottom of such recess is thus obtained. I obtain this upvisn'ily flaring wall J by forming up the construction K out of sheet metal, into the shape shown in the drawing.

L is the float chamber into which the ver- M is the float of the device. Valve I is mounted on float Ill and the air discharge passage 1) from the float chamber L is shown, in this construction, as consisting of the assage way through pipe or tube N into the cat and through the passage ways in' valve I and valve seat H.

O is a well in float chamber M. i

l? is a passage way from well F into well 0 and p is a passage way from well to outlet Q is a manually operated longitudinally movable valve stem previded with valves 9, g, respectively, and is provided with screw threads 9 fitting into corresponding screw threads shell A. When valve stem Q is in the position illustrated in the drawin the valve thereof closes passage we P and valve g closes passa ev way 3). W men the valve stem Q, is moved a d termined distance the valve 51 is withdrawn from its seat an d the pas age way is opened so that the 001 :IltS of the well 6 are discharged into outlet C through such passage way, to clean such well Further movement of the valve stem Q withdraws valve :1 from its seat thereby o enizn-z passage way Pfrom the well F into t 1e well 0, permitting the contents of such well 0 to flow through such passage P and through well 0 and passage In assembling the severe iparts of the device the formed up part K is orced into position in the outlet \J, the float M is dropped thereinto, the top a is secured in place on shell A and valved} is inserted to close the passage ways P, p.\ The diameter of the upper edge j of the conical recess in which the valve seat H is located so great that r the lateral movement of the iloat will not carrv the vslre I o er the edgQ-thatis, outsion in the water of condensation in the float chamber which is not, deposited on the in clined table J settles in the well f. bincd effect of the eculiar construction of the valve seat H an inclined table J and the position of such inclined table above the that a close iit thereof is obtained.
